Granted: 2004-05-25
Abstract: An apparatus for changing bandwidth loading by a bandwidth change amount in a communications interface having elastic and non-elastic call connections where the elastic and non-elastic call connections have associated current cell rates and equivalent cell rates respectively.        The apparatus includes a processor programmed to determine whether the bandwidth change amount is negative or positive. When the bandwidth change amount is negative the processor reduces the current cell rate of each elastic connection and releases at least some non-elastic connections such that the current cell rate of each elastic connection is reduced and the non-elastic connections are released until the total of the current cell rates of the elastic connections and the equivalent cell rates of the non-elastic connections have been reduced by at least the bandwidth change amount. When the bandwidth change amount is positive, the processor increase the current cell rate of each elastic connection and restores non-elastic connections.

Title: Synchronization preamble method for ofdm waveforms in a communications system
Inventor: RYAN DAVID JAMES
IPC: H04B7/26
Filed: 1999-02-23
Granted: 2002-10-22
Abstract: A highly bandwidth-efficient communications method is disclosed that enables remote stations to synchronize in time and frequency to their serving base station. The invention enables a base station and its remote stations in a cell to synchronize in a noisy environment where signals interfere from other base stations and remote stations in other cells. The base station forms a forward synchronization burst that includes a plurality of tone frequencies arranged in a distinctive orthogonal frequency division multiplexed pattern unique to the base station. The unique pattern enables a remote station to distinguish the base station's bursts from other signals present in a crowded area. The distinctive orthogonal frequency division multiplexed pattern can be a Hadamard code pattern, for example. When the a base station has received a signal on a reverse link from a remote station, having significant interference, the base station selectively forms a request signal requesting the remote station to respond with a reverse synchronization burst that includes a plurality of tone frequencies arranged in the same distinctive orthogonal frequency division multiplexed pattern. The base station then transmits the forward synchronization burst and the request signal at a base station reference instant of time to the remote station. The reverse synchronization signals selectively occupy time slots in the transmission frame from the remote station to the base station, that would otherwise be occupied by channel control or traffic signals. Only when the base station requests the remote station to respond with a reverse synchronization burst, does this burst preempt the time slot from its other uses.

Title: Adapter for mounting a fluid handling device on a catheter tubing
Inventor: STROWE ROBERT J
IPC: A61M25/18
Filed: 1999-02-26
Granted: 2002-12-10
Abstract: An adapter of the present invention useful for attaching a fluid handling device to a catheter includes a body having a proximal end, a distal end and an open passageway therethrough. The passageway includes a seat to receive the catheter and a cavity distal to the catheter seat. There is a gasket disposed in the cavity to form a substantially fluid tight seal about the catheter when the catheter is positioned on the catheter seat. The adapter further includes a retainer, disposed on the distal end of the body over the gasket with an opening therethrough that is substantially aligned with the passageway. The opening is sufficient to allow the catheter to pass through into the passageway to engage the gasket and the catheter seat. The retainer has a plurality of flexible projections into the opening that are sized and shaped to engage the catheter and be proximally deflected by the placement of the catheter on the catheter seat. There is a rotatable collar disposed over the retainer on the proximal end of the body, with an open port therethrough that is substantially aligned with the passageway to allow placement of the catheter into the passageway. The collar has a plurality of proximal protuberances disposed to engage the flexible projections and to prevent distal flexion of the flexible projections on the retainer when the collar is in a first position with respect to the body thus to retaining the catheter in the adapter for attachment to a fluid handling device. Additionally, the protuberances are disposed not to engage the flexible projections when the collar is rotated to a second position with respect to the body thereby to allow a distal flexion of the projections and a withdrawal of the catheter from the adapter.

Abstract: A wheel angle of a wheel is adjusted in accordance with the characteristics of tire of the wheel such that a steering characteristics of the vehicle is substantially neutral steer. The wheel angle of a reference wheel of the vehicle (for example, a rear wheel) is adjusted. Next, the reference wheel and a non-reference wheel (for example, a front wheel) are rotated on the tire driving surface of an endless track on which are formed a plurality of plate-like protrusions of a predetermined height. The longitudinal and lateral forces generated in the tire are then measured. On the basis of the wave forms of the rate of change measured in the longitudinal force, a predetermined period is determined from the time when the tire is deformed as the wheel passes over the upward step of the protrusion until the tire is deformed as the wheel passes over the downward step of the protrusion, and data of the lateral force measured within the predetermined period is extracted. The wave forms of the lateral forces of both wheels indicated by the extracted data are superposed, and the direction in which the toe angle of the non-reference wheel should be adjusted is calculated on the difference in the wave forms.
